- Disable port "options" parameter after successful connect. While connected,
a device may install runtime options to control it's behaviour.
- Added enable handlers for the "options" parameter to ensure an attempt to
change the device while connected doesn't enable it.
- Some related code cleanups.
- USB hub: disable device "options" parameter if device is set to "none".
- USB hub: handle device disconnect in runtime_config().
- Removed handling of USB device type in host controllers and external hub.
- Added INT pin init to method init_pci_conf().
- Moved readonly register handling to the common PCI write handler.
- Moved IRQ line reporting to the common PCI write handler.
- Added new structure bx_pci_bar_t that contains all parameters related to the
PCI BARs (type, size, address and r/w handlers).
- Added new methods init_bar_io() and init_bar_mem() to set up the new structure
in the pci device init code.
- Added new method pci_write_handler_common() to handle writes to the normal
BARs and the ROM BAR. Writes to other registers are forwarded to the device
specific PCI write handlers. Removed BAR and ROM BAR handling from the
specific code.
- Added new method pci_bar_change_notify() to execute specific code after BAR
update (vga, ne2k).
- Moved normal BAR handling to method after_restore_pci_state().
- Store pointer to PCI device name in bx_pci_device_c and use it for i/o setup.
- usb_msd.cc: The Device Qualifier is valid for high speed devices only.
- uhci_core.cc: Don't report BX_DEBUG message if the current TD belongs to an
async operation that is still not complete.
- Removed "pseudo device plugin" containing common code and all connectable
USB devices.
- Moved USB device base class and module handling to the Bochs core.
Now loading USB device plugins in usb_common.cc.
- Created separate plugins for each USB device implementation.
- Modified Bochs plugin system to support new plugin type PLUGTYPE_USBDEV.
- Added entries for the non-plugin case similar to the network and sound stuff.
- Since the pci_read_handler() method is identical in most devices, move it
to the base class to reduce code duplication. Only the 'pcidev' device has
it's own implementation (NOTE: it is not maintained yet).
- Minor other fixes and cleanups in some PCI devices.
async mode by default for all USB devices (used by disk, cdrom and floppy).
Whenever we implement a new HC model, it is still possible to set the async mode
to 0 until the async packet completion is working correctly.
- Extended USB callback definition to support different event types sent from
device to HC. Currently we only have the two events "async completion" and
"remote wakeup".
- Implemented event handlers in the UHCI, OHCI and EHCI. For the EHCI version
we currently have no test case.
- The external USB hub now uses this feature at device connect/disconnect.
Now the device change on the hub is correctly detected by the guest OS.
- TODO #1: remote wakeup and async completion for the xHCI.
- TODO #2: event handler for the external hub to make a USB device work on
a chain of hubs.
- TODO #3: the event handler possibly could be used for the packet copy code.
- Moved UHCI async packet functions to usb_common.h for using then on both
UHCI and OHCI.
- Modified OHCI packet handling based on the UHCI implementation.
- Renamed EHCI helper function to avoid conflicts.
- TODO: async packet support on xHCI.
- USB mouse and keypad now return NAK response when idle and there is no change.
- Implemented HID commands for get/set idle duration.
- Fixed NAK behaviour in UHCI and OHCI.
TODO list: USB tablet should also return NAK (doesn't work yet), review xHCI for
the NAK behaviour, accurate implementation of the idle duration
is currently supported per hub at the same time (same as OHCI).
TODO #1: We should support at least one async operation per connected device.
TODO #2: Async packet support for EHCI and xHCI.
ignores connected high speed device (fixes panic with EHCI on guest OS init or
shutdown). The other HC's now panic and disconnect device if the user decides
to continue.
- added method to change port ownership.
- fixed UHCI reset and initialized device pointers.
- added symbol UHCI_FULL_DEBUG to reduce debug output if not set.
- renamed connection handling method.
emulation and usb_uhci.cc implements the setup for the PIIX3 chipset and the
runtime device change code. The UHCI core is required for the EHCI emulation,
since there can be multiple "companion" controllers for USB 1.1 device handling.
